Abstract – The Abrupt advancement in wireless
fractal antenna is altered by introducing an extruded shape up to 2nd iteration for multiband attribute [7].
communication area has expanded the stipulation of compact integrated antennas. This paper depicts the architecture of modified sierpinski carpet fractal antenna up to 3rd iteration which reverberates over a frequency range of 2 to 5 GHz. Contrasting performance parameters like return loss, gain, directivity and VSWR are noticed for the frequencies. A FR-4 substrate with height of 1.6mm and permittivity of 4.4 is used. Microstrip line is used to feed the antenna and simulation is done using ie3d software
2. ANTENNA LAYOUT Fractal antenna geometry is encouraged by nature i.e it retains appearance of fractals that endure naturally. Sierpinski carpet geometry has been used here to design modified Sierpinski carpet fractal antenna up to 3rd iteration. To attain above equitable, first rectangular microstrip patch antenna of L=39.43mm and W=50.72 mm is constructed as shown in figure 1, using equation (1) to (5).
Key Words: Sierpinski Carpet, Rhombus Shape, Gain, Modified fractal, IE3D.
1.INTRODUCTION Antenna is the foremost factor of wireless communication scheme used for imparting and receiving the electromagnetic signals. The antenna categories can be classified based on frequency of function, physical configuration and electrical layout. The prerequisites for modern wireless communication arrangement are small shape low profile multiband antenna, cheap price and large bandwidth. Researchers have advised the fractal pattern used in microstrip patch antenna to meet the above said conditions. In contemporary years, exploration effort has been carried out for several antenna contour based on fractal geometries. These are low profile antennas with modest gain and can be regulated at numerous frequency bands and hence are multifunctional [1]. The style “fractal” measures cracked or erratic remnants. According to Mandelbrot, “a fractal is a pattern made of elements analogous to the whole in some manner”[2]. Selfresemblance tendency of fractal can be seen in its electromagnetic attitude [3]. Fractal based microstrip patch antenna are extensively used for broadband and multiband utilization in tremendous data rate schemes which are known as wide-band communication arrangement [4]. In order to attain the obligation of multiband antenna a modified Sierpinski carpet fractal antenna is created which displays broadband attributes and performance improvement [5]. The layout of modified Sierpinski fractal antenna consist of E pattern fractals up to 3rd iteration and can be used for wideband and ultrawideband functions [6]. A compact Sierpinski carpet
